accelerometry (version 3.1.2)

movingaves: Moving Averages

Description

Calculates moving averages or maximum moving average. For optimal speed, use integer = TRUE if x is an integer vector and integer = FALSE otherwise.

Usage

movingaves(x, window, integer = FALSE, max = FALSE)

Arguments

x

Integer or numeric vector.

window

Integer value specifying window length.

integer

Logical value for whether x is an integer vector.

max

Logical value for whether to return maximum moving average (as opposed to vector of moving averages).

Value

Numeric value or vector depending on max.

Examples

# NOT RUN {
# Load accelerometer data for first 5 participants in NHANES 2003-2004
data(unidata)

# Get data from ID number 21005
id.part1 <- unidata[unidata[, "seqn"] == 21005, "seqn"]
counts.part1 <- unidata[unidata[, "seqn"] == 21005, "paxinten"]

# Create vector of all 10-minute moving averages
all.movingaves <- movingaves(x = counts.part1, window = 10, integer = TRUE)

# Calculate maximum 10-minute moving average
max.movingave <- movingaves(x = counts.part1, window = 10, integer = TRUE, 
                            max = TRUE)
